' Application al a-na 24.1894. Serial No.512,308. (mam To all whom itmay concern: I

is it known that I, JOSEPH ROBISON, a citizen of the United States,residing at G reenbush, Rensselaer' county, New'York, have inventedcertain new and useful Improvements in vaporizing and Ignition Devices;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, suchas will enable others skilled in theart to which it appertains to make and use thesame, reference being hadto the accompanymg drawings, and to the figures of reference markedthereon, which form a part of this specification.

The object of my invention is to provide a new and improved vaporizingand ignition tube for oil or vapor engines.

In the drawings, Figure 1 shows a side elevation of a portion or thecylinder of a gas, oil or vapor engine with a similar view of myignition and vaporizing device and the heatingjacket thereforinjverticalsection; Fig. 2,

an enlarged longitudinal sectional view of my vaporizing and ignitiondevice; Fig. 3, an end view of the ignition'tube taken on line b. b.' ofFig. 2, and Fig. 4, a cross sectional view thereof taken on line a. a.of that figure.

theair being taken in through the opening 3'.

4 shows the body of my vaporizing and ignition device which consists ofany strong metal and is hollow and preferably set in connection with thecylinder 1 in a slanting position. The device or tube 4-has a valvechamber 4' and to the valve chamber is preferably attached an ordinaryvalve 5 and is put in connection with an oil supply 7 by means of a pipe8 or in any other manner desired.

The tank 7 shows the-oil as being. fed by gravity, but the tank 7 shownin dotted lines, shows the oil as being arranged to be fed by suction.to the ignition and vaporizing tube.

This tube 4 may be attached to the cylinder by an anglebush 4" as shown,or it may be flanged and bolted to thecylindcr 1 or affixed theretoin=-any well known manner. Inside .the tube 4.is a copper stem 18 whichis fastened in 'an annular nut 19 and the nut screwed into the largeendof the tube 4, said nut- 19 having a portion of its sides removed asseen at 4". so that there may be ingress and egress past the nut intoand out of the tube 4, and in theend of the copper stem I form a slot20-to take a screw driver that the stem 18 may be easily 'put in andtaken from the tube 4. The end of the nut 19 and copper stem 18 and theopenings 4' will be clearly seen in Fig. 3 which is a view taken of Fig.2 on line b. b.

In the valve chamber 4' is a valve 17 having a triangular stem 14 endingin a circular threaded end to receive the nut 15 and about the circularthreaded end isthe coiled spring .16 which acts to'keep valve 1? closed,its

pressure being but suiiicient to close it when there is no vacuum in thechamber 4. A cross section of the chamber and triangular portion of thestem will be clearly seen in Fig. 4, the triangular portion allowing ofthe oil to flow down to the'valve when it is closed and beyond it whenopen. Referring to Fig. 1 my vaporizing and ignition tube will be seeninclosed in a heating jacket 9 which may be made of sheet iron or otherdesired material and I have. shown its interior surfaces covered with anonconductor of heat 9, preferably consisting of asbestos and under thejackct is a source of heat 10, preferably a vapor burner. 7

At 14 will be seen the ordinary exhaust I valve used with many gasengines and at 11 the opening to the water jacket of the cylinder, thepistongtnd its rod being shown in dotted lines at 12 and 13.

The operation is as follows: The engine will be considered to be workingon the Otto c ole. Valve 6 being open to allow a flow of oil throughvalve 5 and to valve 17, the piston 12 will on its down'or suctionstroke produce}; vacuum in the top of the cylinder which will create avacuum also in thetube 4, and the vacuum will causeithe valve 17 to openand allow a quantity-of oil to enter tube 4 and also cause air valve ,3to open and allow a v and thereby mixed with the air taken in charge ofair to enter the cylinder 1. As the oil. enters tube 4 that tube will-beheated to redness by the source of heat at and the oil will be vaporizedand itsvolume being thus greatly increased it will force itself throughthe. tube 4 and openings 4f" into the cylinder through valve 3.v Oh theupstroke or .com-' pressionfstroko of the piston, the mixture of oilvapor and air will be forced in part out of the cylinder and into thered hot tube 4 where it will be ignited and cause the necessaryexplosion. of the mixture required to keep the engine in motion. Attheproper moment'the exhaust valve will open and the exhausted products ofcombustionwill escape therefrom as in other gas engines a particulardescription thereof beingdeemed unnecessary as I.

claimnothing new ornovel in this pecifica- .tion regarding the exhaustvalve.

I have made. use of the'stem 18 in order to reduce the area of. theopening, in the tube 4 and also as a retainer of the heat in that tube,it assisting to vaporize the oil. \Vhen the oil tank is located belowthe month of the tube 4, as seen in the dotted lines in Fig. 1, thesuction produced by the vacuumin the tube will suck up or causeto riseinto that. tube sulii cient oil for'cach chargeto the tube. It wil beseen, therefore, that my device is eaten lated more'especially for thepurpose of utilizing oil with vapor engines, the oillfind bestadaptedfor use being 150 or proof kerosene oil, and as that oil is perfectlysafe to handle under ordinary temperatures up to 150 Fahrenheit there isno danger of the supply tank giving off explosive vapors as there iswhen gasolene or the lighter oils are used.

With my improvement in vaporizing and igniting the charge, it becomesperfectly practical for engines using'my improvementto be used everywhere without danger from ex plosion and where it is impossible toobtain manufactured or natural gas and where gas-' oline and the lighteroils wonldbe unsafe besides reducing insurance in such buildingswhere-my improvement is used.

I am not aware that any kind of adevice has ever been used with an oilor vapor engine keeping the cylinder as cool as possible.

water jacket used with cylinder 1 is the same taken directly into thecylinder 1 as cool as the surrounding atmosphere, thus tending to partlycool the cylinder thus assisting. the water in the water jacket aboutth'e cylinder in. The

as is usually used with all gasengines and a detailed description isdeemed unnecessary.

Having described my invention so that those skilled in the art to whichit appertains may make and use the same, what I claim, and desire toseizure by Letters Patent, is-' 1. In combination with an oil or vaporengine, an oil conduit arranged to'dis'charge into the engine cylinderand having an automatic intake valve and an oil reservoir connected withsaid valve, and a jacket for said conduit and a source of heat arrangedto heat the 'conduit to a degree suflicient to both vaporize the oil andalso ignite the vapor when mixed with air, said conduit having aninternally located body arranged to absorb a portion ofthe heat,substantially as described.

2. -A vaporizing and ignition devicefor oil f and vapor enginesconsisting of a tube affixed to the engine cylinder and discharging intothe same, and arranged so that oil entered therein will by gravity flow,down the tube,',

and an autoinatic'- .intake valve arranged to ,open on the suctionstroke of the piston, and

an oil tank communicating with said valve and arranged to deliver itsoil thereto by gravity and having a check valve arranged to govern theflow of oil from the tank to the intake valve, and a source of heatarranged to heat the tube to a degree sufficient to vaporize the oil andignite the. same when mixed with air and having a jacket for the tube,substantially as described.

- 3. A vaporizing and. ignition device for oil and vapor enginesconsisting of a tube and a metal stem therein and ports ieadingfrom thetube into the gas engine cylinder and a. valve chamber attached to'thestem and containing an automatic acting valve arranged to open andolo'seon the movement of the engine piston and a check valve arrangedto'limit the supply of oil to said automatic valve and an oil supplydischarging into said valve and a source of heat arranged to heat thetube to a degree sufiicient to both vaporize the oil and ignite thevapor when mixed with air and a jacket for the tube, substantially asdescribed.

In testimony whereof I affix iny signaturein presence of two witnesses.

- JOSEPH ROBISON.
